71c9e0ba42 bcachefs: bch2_extent_ptr_decoded_append() 
This new helper for the move path avoids creating a new CRC entry when
we already have one that matches the pointer being added.

271a3d3a4b bcachefs: lift ordering restriction on 0 size extents 
This lifts the restriction that 0 size extents must not overlap with
other extents, which means we can now sort extents and non extents the
same way, and will let us simplify a bunch of other stuff as well.

b0004d8dfa bcachefs: Factor out btree_key_can_insert() 
working on getting rid of all the reasons bch2_insert_fixup_extent() can
fail/stop partway, which is needed for other refactorings.

One of the reasons we could have to bail out is if we're splitting a
compressed extent we might need to add to our disk reservation - but we
can check that before actually starting the insert.
